to a power operated carriage return mechanism and to certain associated mechanisms for such machines.

One object of the invention is to improve the construction and mode of operation of power operated carriage return mechanisms for record making machines and provide :a novel and improved mechanism by which the carriage of such a machine may be returned bypower either to partially returned or to fully returned position.

Another object of the invention is to provide record making machines having carriage return mechanism operated by power with novel and improved means for stopping the movement of the carriage with the carriage in either of two diiferent positions.

A still further object of the invention is to provide record making machines, having a carriage and power means for imparting return movements to the carriage, with novel. and improved means for disconnecting the power means from the carriage and stopping the return movement of the carriage.

The invention is illustrated in this application as applied to a machine of the Elliott-Fisher type having a paper support which is fixed in the direction of letter space movement of the carriage and a type or key carriage movable across the machine in a right hand direction to letter space and a still further object of the invention is to provide, for machines of this type having power operated mechanism for moving the carriage in a left hand direction to return the same, mechanism for stopping the return movement of the carriage in either partially returned or fully returned positions.

With the above and other objects in view th invention consists in the novel and improved features hereinafter described and particularly pointed out in the claims, the advantages of which will be readily understood and appreciated by those skilled in the art.

The invention will be clearly understood from the accompanying drawings illustrating the invention in its preferred form and the following detailed description of the constructions therein shown.

As thepresent invention utilizes much of the 'mechanism shown in U. S. Patent 1,904,127, referencethereto may be had fora more complete understanding of such features as will be briefly referred to herein.

The'Elliott Fisher machine includes a line space frame formed of front and rear rails l I connected by stretcher bars l9, and supported on tracks l2, forming the side bars of the platen frame, to enable the line space frame to shift towards and from the operator in line spacing direction and return.

A key or type carriage 13 is provided with wheels [4, traversing the transversely extending front and rear rails H of the line space frame, to enable a carriage travel in letter spacing direction and return.

Escapement mechanism (not shown) of any suitable nature, including the customary spring drum, forces the carriage in letter-spacing di rection, under control of the usual keys l5 mounted in the key carriage, as shown in- U. S.

ber 20 being fast on the countershaft l9, and the member 2| being loose on the shaft for axial movement relatively thereto, are interposed between the motor and the carriage l3.

A wide carriage return gear 22 fast on the forward end of the grooved sleeve or collar 23 of the loose clutch member 2|, maintains engagement with a carriage return rack 24 in any position of the loose clutch member 2|, the rack being mounted on an apron 25, projecting from and extending across the. rear end of the key carriage 3.

The clutch members 20, 2| are normally held disengaged by a rearwardly extending latch 26 pivoted on a cross shaft 21, the hooked rear end of which latch takes over the laterally turned upper end of an arm 28 fast on a suitably journaled clutch shifting shaft 29. A clutch shifting finger 30, fast on the shaft 29, extends its upper rear end into the peripheral groove in the sleeve or collar 23. A spring link 3| connected to studs 32 and 33 on the latch 26 and, on the clutch shifting arm 28,.respectively, retains the latch effective, tohold the clutch shifting finger 30 at the clockwise limit of its travel, and the loose clutch member 2| disengaged from the fast clutch member 20.

A rearwardly extending fan-tailed or wedge shaped arm 34, one end of which is fast on the cross shaft 21, enters between the spring anchoring studs 32 and 33, to control the latch 26 and clutch members 28 and 2| ,the wedge shaped arm being rocked by a bail 35, comprising a horizontally extending tooth bar connected by arms to the cross shaft 2'|.'

Complementary trip cams 36 and 31 (Figs. 7, 1 and 4) are adjustably located on the bail 35 to be contacted by tappets 38 and 39 (Figs. 1 and 3),

spaced apart and offset relatively to each other, such tappets being mounted on the travelling key carriage l3. The trip cam 36 is adjustable along the bail 35 to the desired location at which the coaction of the right hand tappet 38 with the cam will occur immediately adjacent the predetermined end of a line of writing, and the trip means 31 is adjustably located at a point approximately corresponding to or slightly in ad vance of the starting point of the line of Writing, to be wiped by the left hand tappet 39 as the carriage, on its return travel, approaches the beginning of a line.

The carriage l3, as it approaches its limit of travel in letter spacing direction, wipes the right For present purposes, the motor I3 may be considered as continuously running, although that shown in Foothorap 1,904,127 is an intermittently running motor, which necessitates the provision of means shown in that patent, for completing and interrupting a motor circuit, not herein shown, though it could be used in place of the continuously running motor.

Immediately upon the engagement of the clutch members 20 and 2|, power from the motor rotates the pinion 22 to return the carriage towards the beginning of a line, and as the carriage on such return, approaches the predetermined left hand limit of its travel, the left hand hand tappet 38 past the right ,hand cam 36, J

thereby rocking the bail 35, shaft 2'! and clutch controlling arm 34 in clockwise direction, Fig. 5. The arm 34, during this movement through its engagement with the stud 32 on the latch 26,

disengages the latch from the clutch shifting i motor driven countershaft I9.

.mentwith the clutch member 20 fast on the? tappet 39, (Fig. 3), wipes past the oppositely faced left hand cam 31 (Fig. 4) complementary to the cam 36 (Fig. 7) near the opposite end of the'bail 35, which cam 37 has been interposed in the path of the tappet 39 by the forward or clockwise rocking of the bail under the influence of the right hand tappet 38 and cam 36. The wiping contact of the tappet 39 with the cam 37 returns the bail and the arm 34 counterclockwise, (Fig. 5), to their normal positions.

The arm 34, upon such return, through its engagement with the stud 33 on the clutch control arm 28, rocks the latter and the clutch finger 30in a clockwise direction (Fig. 5) to disengage the driven clutch member 2| from the driving clutch member 20. The movement of the arm 28 carries the laterally turned lip on said arm forwardly beyond the shoulder of the latch, and the latter then snaps down under the action of spring 3| to retain the clutch members disengaged.

The normal left hand margin stop 4|] (Figs. 1, 3 and 5), mounted on the left hand end of the customary letter spacing rack 4| parallel with and rigidly connected to the rear rail l, arrests the carriage at the extreme limit of its return travel.

. As in the Foothorap Patent 1,904,127, line spacing mechanism adapted for both manual and automatic operation upon such partial return of the carriage.

Line spacing mechanism The line spacing mechanism is based on that shown in Foothorap Patent 1,275,413, August 13, 1918, modified as shown in Foothorap Patents 1,914,885, June 20, 1933, and 1,930,433, October 10, 1933, and is constructed substantially as shown,

in Patent 1,904,127.

A shaft 42 (Figs. 7 and 8), journaled at its opposite ends in vertical brackets 43 (Figs. 1 and 7), projecting upwardly from the rear corners of the line space frame H), II, carries toothed line spacing gears 44 fast thereon and in mesh with racks 45 mounted on the side rails l2 of the platen frame.

At its right hand end (Fig. 7) the line spacing shaft 42 projects through its supporting bracket 43 and has a finely toothed line space ratchet 46 secured-thereto.v A line space pawl carrier or arm 41, journaled on the line space shaft, supports at its radially projecting outer end a line space pawl 48 pivoted at 49, to overhang the toothed periphery of the ratchet 49. on the pawl carrier 4! projects into an elongated recess 5| at the inner end of the pawl to limit its rocking travel in opposite directions.

A spring (not shown, but see Figs. 33 and 35 of Patent No. 1,904,127), attached to the pawl carrier 4! at a point on the opposite sideof the line space shaft 42, normally returns the pawl and pawl carrier to and yieldingly holds them in their normal positions at one end of their travel, as shown in Fig. 7. In such position, the inner end of the pawl 48 contacts an adjustable line space stop 52, to maintain the'pawl disengaged from its ratchet. Adjustment of the stop enables the line spacing interval to be varied.

A driving bell crank 53 is journaled on the line space shaft 42 adjacent the pawl carrier 41, one arm of which driving lever carries a stud '54 entered in a slot 55 in theout'er end of the line spacing pawl 68. The remaining arm of the bell crank 53 (see Fig. 8), projects rearwardly from the line space shaft 42, the outer end of such rearwardly extending arm being connected by a link 56 to one end of an intermediate lever 57 pivoted between its ends at 58 to the adjacent vertical bracket 43. A second link 59 connects the remaining end of the intermediate lever 51 to the outer end of an arm 60 projecting radially from the rear end of a stub shaft Bl (Figs. 1, 3 and 7), journaled in lugs 62 (Fig. 7), depending from a lateral bracket 63 projecting outwardly from the vertical bracket 43.

One arm of an elbow lever 64 fast on the front end of the stub shaft 6|, is hooked to form a terminal for one end of a spring link 95, the 'opposite end of which spring link engages a hook on the lower arm of a lever 65' losely mounted on the stub shaft 6|. An offset lip .61 on the opposite arm of the elbow lever 64 has in the path of a shoulder 68 on the lever 56, the spring link normally maintaining the lip 61 and shoulder 68 in contact.

A draw rod 59 adjustably secured at' its right hand end to the upper arm of the .loose lever 56 on the forward end of the stub shaft 6|, extends transversely of the'line space frame and is confined in a channel formed between the front face of the rear rail II and the 'rear face of the letter spacing rack 4|. The left hand end of the draw rod 69 (Figs. 1, 3 and 5), passes through a guiding eye 19 secured to a bracket ll projecting horizontally from the left hand vertical bracket 43. A cap nut 12 threaded 'on the left hand end of the draw rod 69 facilitates assembly, and prevents disengagement of the draw rod and eye, when the draw bar is slid in one direction.

Should operation of the line space ratchet be prevented for any reason, the spring link 65 will yield to relieve the line spacing mechanism of strain, and prevent breakage.

A catch I3 (Figs. 1, 3 and 5), is adiustably locked at any of several positions along the left hand end of the draw rod 69, to coincide, approximately, with the position to which the left hand margin stop 49 is set along its .rack 4|.

A coacting catch 'Hl'pivoted at 7 5 to a hanger l6 projecting from the left hand side of the carriage I3, is normally held in position to engage the catch 13, by a spring", one end of which is attached to the tail of the catch 14 to hold the catch at one limit of its rocking movement determined by a stop pin Il The depending hook shaped catch 14 is A stud 50' cated in advance of the adjustable carriage stop 18 (Figs; 1 and 3) which coacts with the left hand margin stop 40, when'the key carriage is being returned tothe beginning of a line, so that as. the key carriage approaches its left hand margin, thedepending catch 14 will first engage its coacting catch 13 near the left hand end of the draw rod 69 and pull the latter catch together with the draw rod 69 to the left. The draw rod, through its connection with the loose lever 66, rocks the latter and through the spring link 65 rocks the stub shaft 6| in the same direction to actuate the connections Bil, 59, 51 and" 59. Through these connections the bell crank 53 is advanced in counter-clockwise direction (Fig. 7) first rocking the line space pawl 48 on .its pivot 49 to effect its engagement with the toothed periphery or the line spacing ratchet 46, after which continued advance of the bell crank 53 turns the ratchet, the shaft 42 andgear wheels to advance the key carriage.

As the bell crank approaches the limit of its advance rotation, the line space pawl-advancing therewith, collides with an abutment 79, which arrests farther advance of the pawl and its train of mechanism back through lever 64, the pawl, by reason of such'contact, being forced more firmly into engagementwith'the ratchet 46 to lock the ratchet against continued rotation, thus preventing overthrow of the carriage in line spacing direction.

Substantially simultaneously with the arrest of the line spacing operation, the adjustable carriage stop 18, (Figs. 1 and 3), contacts the left hand margin stop 49 to arrest the carriage, at which time'a lateral stud 89 extending forward- 1y on the depending catch 14 has escaped past and is caught behind a by-pass cam 8! on the margin stop 49 as shown in Patent 1,904,127. The carriage escapement mechanism holds the carriage at the end of its extreme left hand travel,

as limited by the margin stop with the line 69 and. the catch 13' to 'ther nomal positions.

During this movement of the parts, the pawl 48 is rocked to disengage it from the ratchet 46 and the pawl carrier and pawl swing rearwardy with the lever 53 until the pawl is arrested by contact with the adjustable abutment 52.

To enable the operator to effect a motor driven carriage returnfrom any point intermediate between the beginning and end of a line, it is customary to provide a special Carriage return key, depressionof which operates a finger to rock the carriage return clutch bail 35 and effect an engagement of the clutch members 29, 2| (Fig. .5), to connect the motor with the carriage return pinion 22.

The clutch members are disengaged upon the arrival of the carriage at the beginning of :a line,

by the wiping'contact of the tappet roll 39 (Fig' 3), with the cam 31, ,as'heretofore explained.

The foregoing is, in the main, old, and con- .stitutes apart of the presentinven'tion only insofar as it cooperates with the novel features now to be set forth.

Partial carriage return It may often be desirable, in accounting operations, in paragraphing, or for other reasons, to effect a return movement of the carriage of a typewriting machine in contra-letter spacing direction from any advanced position to a precedent position short of a complete return to the beginning of a line.

To this end, I have contrived a means under control of the operator which not only effects connection of the power with the carriage, at any desired point in the letter spacing travel of the carriage beyond the place at which the carriage will be arrested short of a complete return, but also simultaneously disables the normally effective line space initiating device, and substitutes another therefor.

Furthermore, such operator controlled means shifts an arrester from idle to effective position, and may position a normally ineffective clutch disabling control for operation.

Referring to Figure 5 of the drawings, I utilize the special key I heretofore provided to initiate the return movement of the carriage from any point short of the end of a line, as a partial carriage return key, it being obvious that the former carriage return key could be retained, and a second key arranged to contact my improved partial carriage return mechanism.

In either event the key lever IOI of the special key I00 is pivoted at I02 (Fig. to the rear of the key carriage I3, a bell crank I03 being pivoted co-axially with the key lever, and having an ear on one arm connected by a spring link I04 with a similar ear on the tail of the key lever.

Should the bell crank be blocked from operation, the spring link I04 will yield to avoid straining the bell crank I03 and its connected parts.

A depending arm of the bell crank I03 is slotted to embrace a wrist I05 on an arm I06 fast on, and projecting radially from a shaft I0I extending part way across the carriage and journaled in flanges I08 projecting upwardly from the apron supporting the carriage return rack 24.

The inner or right hand end of the shaft I0I carries a finger I09 depending to a point behind the universal clutch bail 35, the finger travelling with the carriage and being operable upon depression of the key I00, to rock theclutch bail forwardly, in any position assumed by the key carriage in its letter spacing travel, against the tension of a return spring IIO (indicated by dotted lines) coiled about the shaft.

A stud II I projects laterally from the horizontal key lever IOI, and passes through a slot I I2 in the horizontal arm of the bell crank lever I03 parallel with the key lever, the spring I04 maintaining the key in its normally elevated po- 'sition, determined by contact of a face on the key lever with the underside of a slotted plate I I3 through which the stem of the key passes.

In normal position, the stud III occupies the upper end of the slot H2 in the horizontal arm of the bell crank lever, as shown in Figure 5.

The spring link I04 has the additional function of permitting the bell crank I03, arm I06 and ball operating finger I03 to rock to their normal positions whenthe carriage I3, on its return, wipes its disengaging tappet 30 past the left hand cam 31,

even though the key I00 is accidentally or purposely held depressed, thus to enable the automatic disconnection of the motor from the carriage when the latter has been arrested in its left hand marginal position.

Nor can the finger I09 become effective to engage the clutch members 20, 2 I, until the carriage has advanced in letter spacing direction a sumcient distance to withdraw the disengaging tappet 39 from the cam 31.

One means to enable the operator to simultaneously shift the normally efiective line spacing catch I4 (Figs. 1 and 3), to idle position and substitute an earlier operating catch therefor, and also to introduce an' earlier acting carriage arresting member, controlled from the special carriage returnkey I 00 which throws in the clutch connection between the motor and the carriage, whereby the operator, by depression of a single key, may effect all three results, is as follows:

A thrust bar II4 (Fig. 5), the upper end of which is pivotally-attached at II5 to the horizontal arm of the bell crank I03, depends therefrom, its lower end passing loosely through an eye II6 for guidance and having a collar III adjustably secured thereto to contact the eye. The eye H6 is clamped to the lever H8 in a position between the ends of said lever, the front end of which lever is pivoted at I I9, to a hanger I20 depending from a bracket I2I secured to the left hand side of the travelling carriage I3. The rearward free end of the lever II8 overhangs a leftward extension I22, (Figs. 1 and 3), of the travelling catch I4. The left hand end of the extension I22 is shouldered, as at I23, to coact with the catch I3 adjustable along-the pull rod 69, but is normally held in elevated position by the spring 11, so as toescape past the catch 13 without contact therewith, when the carriage is returning to its normal left hand marginal position. 7

Depression of the key I 00, however, not only rocks the bell crank I03 and finger I09 to shift the universal clutch control bail 35 forwardly, and thus connect the clutch members 20, 2| to enable the motor I6 to drive the carriage I3 in letter spacing direction towards the beginning of a line, but also forces the thrust rod I I4 downwardly to press its collar III against the eye II6 fixed to the catch reversing lever H8. Such pressure rocks the free end of the reversing lever IIB downwardly and the lever, in turn, rocks the extension I 22 downwardly, which raises the catch As a result, the shoulder I23 of the partial return catch or extension I22 is brought into line with the catch I3 on the line space draw rod 69, and the catch I4 is displaced from its normal position.

Obviously, the displacement of the normal catch I4 is without significance, as, irrespective of its position, it would not function if the partial return catch I23 is in effective position, the partial return catch being arranged in front of the left hand margin catch I4, when the carriage is returning to the left.

Control by the operator of the interceptor carriage stopping means is conveniently effected as follows:

A strap I25 pivotally connected at its upper end, as at I26, to the eye H6, for instance, depends below the line space catch reversing lever I I0, and is connected at its lower end to the leftwardly extending end of an interceptor stop I2I.

attains! This interceptor stop is loosely pivoted at its right hand end, at I28 (Figs. 1 and 3) t9 ii'ame or casing of the carriage and is arranged to ena an abutment I29; projectin upwar ly fr m a-horizontal plate I30, secured at its rear edge to the rear rail II to stop the carriage in partially returned position. The strap I'normal1y suspends the free left hand end of the interceptor stop at such a level as to clear said abutment.

The length of the interceptor stop member is such as to engage the abutment I29 to arrest the carriage at a point in the return movement of the carriage before it reaches fully returned position as for paragraphing, for example.

In the form shown in the drawings, the care riage, upon a partial return, is arrested about one and one-half inches to the right of the extreme left hand margin obtainable in the machine.

Obviously, such distance can be varied by adjusting the left hand margin stop 40 to the right from its extreme left hand adjustment, and the provision of means (not shown) for adjusting the banking abutment or the interceptor stop will admit of other relative variations between the point where the first line of a paragraph commences, and the extreme left hand margin.

In order to actuate the carriage return bail 35 to disconnect the clutch members 20, 2| just before the carriage is stopped by the engagement of the interceptor stopI21 with the abutment I29, the machine is provided with a longitudinal: ly rnovable rod I3 I. The left hand portionof this rod is suspended for longitudinal movement upon the interceptor stop I21 by meansof a bracket I32 secured to the interceptor stop and having a rearwardly bent portion at the lower end thereof which engages in a slot I33 formed by a cut-out in the rod I31 and a strip I34 secured to said rod. The right hand end of the rod I3I is pivoted to an arm I35 secured to a substantially vertical rock shaft I36 (see Figs. 2 and 4). This rock shaft is mounted to turn in a bracket I31 secured to the frame of the carriage and an arm I is attached to the upper end of said shaft. To this arm is pivoted a thrust rod I39 passing through an opening in the down-turnedportion of an angle plate I40 secured to the framework of the carriage and the rear end of said rod I39 is arranged to engage the carriage return bail Whenthe rod is moved rearwardly. The arm I35 is acted upon by a coiled spring IGI which normally maintains the rod, I3I in its left hand position determined by the engagement of the arm I38 with a suitable stop on the framework of the carriage and the rod I39 in advanced position out of engagement with the carriage return bail.

Thus the rod I3I is mounted on'the carriage and moves with the carriage during the return movement thereof. The left hand end of the rod I3I is arranged to engage an abutment I42 on the frame during the return movement of the carriage when said rod is in its lowered position.

The left hand end of the rod is held in elevated position so that it does not engagethe abutment I42 during the full return movement of the carriage. The interceptor stop I21 is then held in elevated position in the manner above described and the left handend of the rod I3I is held elevated therewith. When the interceptor stop I21 is depressed by the depression of the key I00 the left .hand end of the rod I3I is depressed into position to engage the stop I42.

Upon the release of the key, the latch holds the lever H8 and all of the parts controlledfrom the lever in position during the partial return movement of the carriage.

The means for releasing the'latch durin the early part of the next advhl oemovement of the carriage comprises a 1everI50 (see :Fig. 6) pivoted at I52 upon the plate 1A6 and arranged to engage theredgeof the latch when swung in a counterclockwise .diregtion from the position shown in said figure. {The lever I is held in position out; of engagement with the latch by .meansof .a coiled spring I53 ,andits movement under the action of said spring is limited vby means of a stop screw 15; threaded into the plate I46 v 1 The'lever I50 gis :swung in a countereclockwise direction (Fig. 6) during the early part of the advance movement .of the carriage by means of a lever I55 pivoted at I56 upon a block attached to a projection or arm I51 on the line space frame, the forwardend'of which lever is arranged toengage the upturned rearend portionof lever I50. The .lever I55 is provided with a' beveled faceI58 whichis engagedby theplever I5!) during the return movement of the carriage. The movement 10f the 'lever'I55 about itspivot I56 in a ,countere-clockwisedirection (Fig, 6) is limited by .means of abracket [:50 secured to the block on the arm I51 and the lever is actedupon by a coiled spring I60 which normally'maintains the lever in engagement Withthe bracket I59.

iDurihe t e ea y part. f th nox adv nce-mowment of the carriage the rear end of the lever I50 engages the forward end of the lever I55 which is then held in engagement with the bracket I 59 thereby preventing any pivotal movement thereof in a counter-clockwise direction.

The lever I55, therefore, swings the lever I50 in a counter-clockwise direction (Fig. 6) thereby actuating the latch to disengage the shoulder thereon from beneath the plate I46. This releases the lever I I8 so that said lever can rise to its normal position thereby restoring to normal position all of the parts controlled by said lever.

Figures '7 and 9 of the drawings show a modified construction for effecting the disconnection of the members 20 and 2I of the carriage return clutch when the carriage reaches the end of its return movement. In this mechanism the carriage return bail 35 is swung rearwardly to effect the disconnection of the members of the clutch at the completion of the return movement of the carriage by means operated by certain parts of the line space mechanism. As shown in this figure, a thrust bar I6I is pivoted at I62 to the upper arm of the lever 66. This thrust bar passes through a guide in a bracket I63 secured to the bracket 43 by means of the stop I9. Th left hand end of the thrust bar I6I is provided with a beveled face I64 arranged to engage the right hand end of the carriage return ball 35 when the thrust bar is moved to the left from the position shown in Fig. '7.

As the carriage completes its return movement the draw-rod 69 is moved to the left (Fig. 7) by the engagement of a contact on the carria ge with the catch I3. This movement of the draw-rod swings the upper arm of the lever 66 in a. counter-clockwise direction (Fig. '7) and moves the thrust bar I6I to the left through the guide I63. During this movement the beveled surface I64 of the left end of the thrust bar is engaged by the right hand nd of the carriage return bail 35 and said bail is swung rearwardly to disengage the members of the clutch. As the draw-rod 69 is moved back to the right during the early part of the next advance movement of the carriage the thrust bar I'6I is moved to the right therewith, thereby restoring the same to its normal position.

The machine is preferably provided with an escapement or letter feed mechanism of the type disclosed in the patent to Foothorap, No. 1,203,519, dated October 31, 1916, and controlled from the several letter and numeral keysof the type mechanism and from the space bar I65. The machine is also provided with an escapement release key I66 and connections between the same and the escapement mechanism as shown and described in said patent.

With this construction, when the writing is completed for a line before the carriage reaches the limit of its right hand movement and. the operator desires to return the carriage to its fully returned position, he depresses the release key I66 allowing the carriage immediately to move to the right to the limit of its movement and thereby to throw in the carriage return mechanism or he repeatedly depresses the space bar I65 to secure the same result. When he desires the carriage return mechanism to return the carriage to partially returned position, he depresses the partial return key I00. Thus the carriage may be selectively returned to fully returned or partially returned position at the will of the operator.
